The day dungeons appeared on Earth, everything changed! From ordinary beasts to monstrous ones, attacks were common throughout the globe, and no one was safe.

After countless studies using these beasts as subjects, Humankind developed a serum capable of awakening incredible abilities in humans, leveling the battlefield.

With the serum came heroes and villains, those who wished to use their powers for good or bad.

The Garmony Upper School was a place for the elite with the sole purpose of creating heroes to fight the villains and explore more of the dungeons after the beast attacks increased for no apparent reason.

Damian Romero, a youth who received the serum after turning 18, yet got no unique ability. It was not uncommon for one to not receive power, but it was still a blow to one's pride.

He went rogue after the news, drinking alcohol and having a good time with women, and it was at that moment, when he was putting his toy to play, he got a surprise.

The tea smelled good, and it tasted good too. Damian was more than happy to have a treat like that while meeting the current leader of Lemoria.

Ingram was still clueless as to why an enchanter in ascension like Damian and his granddaughter were there, to begin with.

"Emma," Ingram said, staring at her thoughtfully, "What happened?"

The idea of something or someone hurting his granddaughter was too much for him. Damian could feel the pressure inside the room rise and the worries on Ingram's face.

"Relax, there's nothing to do with me, but we might be able to help the city as a whole," Emma said, moving her head to her servant, "Tell him about what you saw."

The servant was still scared. It was hard to put the words together when facing such high authority. Emma could see that, so she grabbed her hand for more comfort.

"I-I was returning to Lady Emma's mansion when I saw it! A man killing a group of people near the road, doing some evil stuff."
